T9 al?, whom it may concern.'

through the plunger-head and substantially Be it known that I, ELIsHA R. KEER, reon the line 5 5 of Fig. 4. Fig. 6 is a crosssiding at Erin, in the county of Houston and State of Tennessee, have invented certain new and useful Improvements in Baling- Fresses, of which the following is a specification.

My present invention relates to improvements in that type of baling-press generally disclosed in my Patent No. 745,862, granted December 1, 1903; and it primarily seeks to provide a press of the character stated of a simple, economical, and durable construction, in which the several parts are coperatively arranged to effect the practical operation of compressing the fibrous material expeditiously under a minimum expense of labor and time.

In its generic nature my invention comprehends an improved' construction of plunger-head having a special design of impacting-face and means for permitting a downward yielding of the upper part of the front end of the plunger-head under excessive pressure thereagainst of the material fed into position to be pressed.

In its more complete nature my invention embodies a peculiar construction of tucker or holdback means for engaging the upper edge of the rear end of the bale being made when the plunger recedes and a peculiar form of retainer devices that cooperate with the tucker or holdback and which have a special construction whereby they can be easily placed .in an operative position or removed without the use of fastener bolts or screws.

In its still more subordinate Jfeatures my present invention consists in certain details of construction including al special arrangement of the plunger-actuating mechanism, all of which will be hereinafter fully described in detail, specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my improved press, the plunger being shown in the position of compressing the bale. Fig. 2 is a horizontal section of the same, taken substantially on the line 2 2 of Fig. 1, the parts being in the position shown in Fig. 1. Fig. 3 is a horizontal section of the baling-chamber, the plunger being shown as moved back and the bale held in position by the tucker or holdback and the retainer devices. Fig. 4 is a longitudinal section of the parts shown in Fig. 3. Fig. 5 is a transverse section taken section of the baling-chamber, taken on the line 6 6 of Fig. 3 and looking in the direction of arrow a. Fig. 7 is a detail perspective view of one of the side retainers. Fig. 8 is a detail section which illustrates how the pivotal end of said retainer is detachably connected with the press-frame. Fig. 9 is a detail view of the tucker or holdback. Fig. 10 is a detail perspective view of the front end of the plunger with the iron cap member and the iron facing-plate, hereinafter described, removed. Fig. 11 is a detail view of the cap member. Fig. 12 is a plan view of the plunger-actuating mechanism. Fig. 1 3 is a transverse section thereof on the line 13 13 of Fig. 2. Fig. 14 is a longitudinal section thereof, and Figs. 15, 16, and 17 are detail views of several of the parts hereinafter specihcally referred to.

In my present invention the most essential improvements are in the construction of the plunger-head and its cooperative connection with a special arrangement of retainer devices.

In baling-presses of the character before stated from practical experience I have found that an overcharge of hay through the throat or intake of the baling-chamber effects a very great strain on the press-box and plunger-head and frequently produces a breakage o f said parts and often causes the plunger-head to frictionally engage with the walls of the baling-chamber and to hug the same so tightly that it does not make the rebound when the pressure strain is thrown oli. This hugging or wedging of the plunger-head is greatest at that part of the baling-chamber where the hay wedges between the plunger and the bale-chamber and is generally at the top wall of the said chamber. To reduce such objectionable action to the minimum and to render the rebounding of the plunger the more positive, I form the plunger-head with its upper forward part downwardly yielding when an excessive or overcharge strain is met.

In carrying out my present invention I provide a press or baling box which in its general arrangement is of the conventional type and, as shown in the drawings, comprises the longitudinal foundation-sills 1 1, a pair of upper longitudinal sills 2O 20, disposed in the vertical plane of the ground- 'sills 1, the vertical brace-bars 30, and the hori- IOO IIO

zontal upper and lower transverse beams S and Q, all of which. are securely clamped by the rods 50 and nuts 60 in the usual manner.

l2 designates the usual filling opening or intake for the baling-chamber and preferably has one of the sides of its hopper 12 extended to facilitate the feed of the hay to the opening l2.

The plunger A, the construction of which is best shown in Figs. 5 and l0, has its head (L of solid wood or put together in section and its front face preferably faced by an iron plate @1 a, as best shown in Figs. 2, 3, and 4, and the said plunger is formed with a deep recess a in its forward end and with a shallow recess (L2 in its front face that extends down from the base of the recess e and the full width of the said recess a, as shown. Seated within the recess a is a cushioning means, which may be rubber' blocks, but preferably is in the nature of stout coiled springs c, that seat in the circular sockets ai* a in the base of the recess a.

B designates an angle-iron cap-plate the top portion b of which is adapted to fit within the recess a and to rest upon the springs C, as clearly shown in Fig. 5, from which it will also be seen the cap B is held in place by the long rodsjlf, that pass through the apertures 1) b in the cap part b and have their heads engaging the countersunk seats b2 b2. rlhe tension of the springs c c is regulated by the adjustment of the nuts f 2 on the lower ends of the rodsf, which rods extend down through the head a and project into the cavity a" in the bottom thereof, as shown. The front part b3 of the cap forms an apron that fits into the recess on the front of the plungerhead.

To let out trash that might otherwise accumulate in the mortise a', the front face of the head has a vertical cavity a5, that extends the full front face thereof, as shown, and to assist in throwing the hay toward the -center of the bale-chamber the upper corners of the head a are chamfered or beveled, as indicated by a; 0c.

The head ct has the usual longitudinal cavities e e in the opposite sides to receive the retainers hereinafter referred to.

So far as described it will be readily apparent that in the operation of forcing the plunger-head a against the fibrous mass and pressing the said mass under the top of the baling-chamber, as indicated in Fig. A2, should any of the hay by reason of overcharge or otherwise wedge between the chamber-top and the plunger-head the upper front portion ofthe head will readily yield, and thus positively overcome an excessive strain, as also danger of the head hugging the chambertop or becoming wedged to that extent that it will fail to rebound. The yielding of the upper front end of the plunger-head also serves another function in that it facilitates the automatic adjustment of what I term a tucl er, which acts as a holdback by reason of engagin@r the upper rear edge of the compressed ba ewhen the plunger recedes therefrom.

The tucker D comprises a stout iiat springmetal plate having the width of the balechamber, and it is made fast at its rear end d to the top cross-sill 8a by the bolts 8b and has Aits front end held to rest upon the cross-sill 8 adjacent the throat of the baling-chamber.

The front end of the plate D is bent rearwardly and downwardly at an a'cute angle, as at d, whereby to form a beveled-faced hook and which preferably projects down into the path of movement of the upper front end of the plunger-head, but need extend only sufliciently low to lap over the rear upper edge of the bale.

By forming the member D in the manner shown and securing it as stated a charge of hay will easily raise it with the weight of a man thereon, and after the plunger rebounds the hook end d will snap down over the back edge of the compressed mass and hold it from expanding, it being understood that the tucker rises and falls at each charge of the plunger.

In my present construction of press the retainers G each consist of a flat plate having the forward portion of its inner edge inclined, as at g, to enter within the baling-chamber and the cavities e e in the plunger-head, and the outer front edge has the right-angled wings or extensions g g, that limit the inthrust of the said retainers and are formed with horizontal recesses g5 on the outer face, for a purpose presently explained. The rear ends of the retainers G have integral rightangled extensions or rounded pintles g2 g2,

whose bearing-faces-g3 detachably seat to rock within the sockets h, formed on the inner face of plates H, made fast to the side boards of the baling-chamber by screws or bolts, as best shown in Fig. 8, and the outer faces of the plates 'H have loops h5, through which pass the stout flat springs l, that are fastened to the sides of the baling-box and have their front ends loosely seated in the recesses g in the members g.

By reason of the peculiar construction and arrangement' of the retainers G they can be readily removed o1 placed in position for use and held without the use of bolts or other like devices, since the springs I firmly hold the ends in the sockets formed in the sides of the press-box, it being understood by simply pulling the springs l back the said ends (73 can be readily removed from the pockets they engage. The wings or extensions g g/ are preferably formed by screwing a plate upon the outer edge of the flat member G, but may be formed integral therewith, as shown in my patent above referred to.

In connection with my improved construc- IOO IIO

'tion of plunger-head and retainer devices I prefer to use the plunger-actuating mechanism shown and which I shall now describe in detail.

Theplunger-actuatingmechanismis mounted upon the outer end of a pair of groundsills l, the forward ends of which extend beyond the rear ends of the ground-sills that carry the press-box, and the said sills ld are fixed to the outer end of the transverse bottom timbers, that extend transversely from and are connected to the rear ends of the sills la, as shown.

Upon the outer ends of the sills 1a is mounted a foundation-framing composed of two cross-timbers 2 2, located on the under side of the sills la, two cross-timbers 3 3, that seat in mortises in the upper face of the sills la, two upper cross-timbers 4 4, held apart by space-blocks, all of which are braced and clamped to form a rigid foundation by the vertical bolts 5 and horizontal bolts 6, made fast by the clamp-nuts, as shown.

The pitman P has the usual pivotal connection with the plunger-head and has its outer end passed between the inner crosstimbers 3 and 4, and its outer or free end is formed with a concaved seat p, adapted to be engaged by either of the ends l Z of the arms L, that-project radially and in diametrically opposite directions from a hub member L, journaled on the foundation-framing.

The pitman is guided by the timbers 3 and 4, and at a suitable distance from the concaved or power end it has a wedge-shaped stop p, adapted to wedge in between the said timbers 3 and 4 (see Fig. 15) and to act as means for checking the rebound of the pitman as it moves backward from the pressed bale.

The hub portion L of the power device is journaled in semicircular bearings 3a 4a, formed in the outer ones of the cross-timbers 3 and 4, and are held to said bearings by the semicircular strap-bands 10, secured to the timbers 3 and 4, and the semicircular bands 10a, that are bolted to the bands l0, as shown in the detail Fig. 16. The hub L has offsets or iianges Z5, which engage the semicircular flat iron bands 1021, that are fitted in the timbers 3 and 4 to form a steady and durable bearing for the said power-hub L. The upper end of the upper hub L/ terminates in a flat disk L2 to receive the sweeplever M, which is made fast by the bolts fm fm, as shown.

R designates a strong helical spring connected at one end to the plunger and at the other end to a stationary portion of the frame to assist the plunger in making rebound.

From the foregoing, taken in. connection with the accompanying drawings, it is believed that complete construction, the manner of operation, and the advantages of my present construction of press will be readily apparent to those skilled in the art to which it appertains.

My present invention, so far as I know, differentiates from what has been heretofore provided in the peculiar construction of the plunger-head, the tucker and its coperatlon with the said head, and the sideretainers. It is understood that changes in the details and modifications of the specific correlation of parts shown in the drawings may be made without departing from the scope of the appended claims.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, is-

l. In a baling-press of the character described, a plunger whose front upper portion is\mortised, a head portion mounted in said mortise downwardly yieldable, the said plunger below the mortise being vertically slotted for the purposes described.
